To all' whom "it may concern:

Be it known that we, vJosiirii B. LONG and CHRISTOPHER WRIGHT, citizens ofthe United e 10 cient and si htly radiator for use on automobiles, an vwhile the following description will be limited thereto, still we desire to have it 'understood that we reserve to ourselves, the exclusive right'to use the several features of the invention for any and all purposes for which they may be found to be useful. f

lIn a radiator for automobiles, efficiency, from a mechanical view point is, of course, of prime importance, but appearance is scarcelyy les's so, from the standpoint of cominercia success. Occupying, as it usually does, the front and most conspicuous place on the machine,it` gives character "thereto, to a certain extent, and must be ornamental or else it cannot be a commercial or practical success. There are now in use, many types, presenting many appearancesand one t e, which'is in high favor, from the standpoint of appearance is what is known as the honey comb or cellular.

The object of the present invention is to provide a radiator of this honey comb or fcellular appearance and eiiiciency, having at the same time, the advantages of a tubular radiator from a functional standpoint and to provide a radiator` having certain votheradvantages that are not found in either the honey comb or the tubular, strictly so ca-llied, as these are found on the market toa To these ends the invention consists in the features of novelty that are hereinafterdescribed, with reference to the accompanying drawings, which are made a part of this specification and in which:

Figure 1 is a conventional re resentation of a' radiator on a small scale, emllxodying the invention. Fi 2 is a horizontal section on the line 2 2 Fig. 4, of a portionof a radiator embodying the invention. Fig. 3 is a hori-l zontal section of a fragment thereof on a larger scale on the line 3-3, Fig. 5. Fig.- 4 is a front elevation of what is Lshown in Fig.

2. Fig. 5 is a front elevation ofwhat is shown .to thedirection of travel.

in Fig. 3. Fig. 6 is a horizontal section on the line 6 6 Fig. 7 and Fig. 7 a front elevation of fragments showin a modification.

The radiator, as 'a Who e, may be of any desired shape or configuration, but comprises, as usual, an inlet chamber, or header A into which the water to be cooled is introduced through a suitable' connection, coming from the cylinderfjacket and an outlet chamber, or header B from which .it is returned to j.said jacket, through a suitable connection,

having meanwhile assed from the inlet chamber to the out et chamber through a bank or series of pi es or'tubes C. In the drawings, we have shown these tubes as bein vertical, with one header above the otv er, but the horizontal. arrangement of tubes with the headers on opposite sides of the radiator is within" the sco e of the invention and so'familiar to radiator and automobile builders and users as to require no illustration.

The term headers is used in this -specification in the sense in which it is customarily used byj those skilled in the practical, art of making, using and selling radiators for automobiles, as Well as for other urposes, and steam boilers. They consist o boxes, tubes, or other chambers into and from which the circulating medium is delivered, respectively.

In Figs. 6 and 7 we have shown the tubes as being of cylindrical cross section, while in Figs. 2, 3, 4, and 5, we have shown them as being of oval or elliptical cross section, with their major axes disposed forward and backward. In other words, they are edgewise The elli tical or oval tube has an advantage over tllfe cylindrical tube in that it has a greater radiating efficiency and this efficiency is increased by vthe described arrangement of tubes, with their major. axes forward and backward, thereby presenting broad (almost flat) surfaces, over 'which the air currents pass and with which they have contact as the car advances. It should be borne in mind, however, that in its broadest aspect, cylindrical tubes are within the scope of the invention.

In the drawingsv we have shown the tubes as being arranged in rows extending from side to side of the radiator. These tubes alone would not dprovide the necessary radiating surface an of course, would not present the desired honey-combed appearance at the front of the radiator. To accomplish both of these things we use, in connection with the tubes, a plurality of sheet metal strips Dwhich extend from side to side of the radiator and are crim ed or corrugated transversely of'their lengt Each of these Strips v is provided with an opening through which each of the tubes passes Vso that each strip embraces all the tubes. Thus arranged, each of the tubes is braced against other tubes and the result is an extremely rigid structure. All of the strips are similarly corrugated and are strung on to the tubes in such manner that similar corrugations of adjacent strips are reversely presented (upward and downward alternately) and so thatin the completed structure the summits of the corrugations of adjacent Strips contact with each other, leaving between the vstrips openings of square, diamond, or other shape, depending upon the shape of the crimps or corrugations. The openlngs through which the tubes pass extend through the summits of some of the corrugations and in addition to these corru ations the strips have othercorrugations d etween the tubes. The several corrugations afford the necessaryvextended radiating surface and when arranged' as described present the desired honeycombed appearance. The strips are perforated at numerous points as shown at cl for the purpose of permitting the heated air to pass upward through them.

What we claim as new and desire to secure by Letters Patent is:

1. Ina radiator, the combination with the headers, of a plurality of tubes connecting them and arranged in a row extendin 1r'rom side to side of the radiator, and a plura ity of a plurality of strips extending from side toside of the radiator, each of said strips having openings throughwhich all of said tubes ass, said strips being corrugated transverse y of their length from edge to edge and so ar-v' ranged that the summits of the corrugations of adjacent Strips contact with each other.

3. In a radiator, the combination with the headers, of a plurality of tubes connecting them and arranged in a row extendin from side to side of the radiator, and a plura ity of strips extendin from side to sideof the radiator, said strips ein corrugated transversel of their length and having openings extend? ing through the summits of some of the cor-I rugations, through whichopenings the tubes' pass,- while other of the corrugations are located between the tubes, the strips being so arranged that the summits ofthe corrugations of adjacent strips contact with each other. a:
